Configuring the Switch
3-86
• Migration – If at any time the switch detects STP BPDUs, including
Configuration or Topology Change Notification BPDUs, it will automatically set
the selected interface to forced STP-compatible mode. However, you can also
use the Protocol Migration button to manually re-check the appropriate BPDU
format (RSTP or STP-compatible) to send on the selected interfaces.
(Default: Disabled)
Web – Click Spanning Tree, STA, Port Configuration or Trunk Configuration. Modify
the required attributes, then click Apply.
CLI – This example sets STA attributes for port 7.
VLAN Configuration
Overview
In large networks, routers are used to isolate broadcast traffic for each subnet into
separate domains. This switch provides a similar service at Layer 2 by using VLANs
to organize any group of network nodes into separate broadcast domains. VLANs
confine broadcast traffic to the originating group, and can eliminate broadcast
storms in large networks. This also provides a more secure and cleaner network
environment.
An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the
network, but communicate as though they belong to the same physical segment.
VLANs help to simplify network management by allowing you to move devices to a
new VLAN without having to change any physical connections. VLANs can be easily
organized to reflect departmental groups (such as Marketing or R&D), usage groups
(such as e-mail), or multicast groups (used for multimedia applications such as
videoconferencing).
